My Norcold 1200LRIMD won't switch from LP to AC. Fuses are OK.

You have to answer the obvious, are you plugged into shore power? Did it work previously?

I assume you have the control set to AC only, not auto.

The service manual might help you diagnose the problem. https://norcold.com/wp-content/uploa...68C_020807.pdf

Where's Old-Biscuit? He is the appliance expert on irv2.com.

As suggested.......

Plugged into shore power?
Verified you have 120VAC at outlet fridge is plugged into?
Verified you have 120VAC on Both sides of AC Fuse (F3)....good contact with clips?
All of above check out.......then circuit board is issue

EDIT Old biscuit was typing while I was he forgot more about rv appliances than I know lol. Maybe fuse I described is 120v .

It would be on AC circuit breaker fuses 12v for control power. Most are not wired to work on inverter. I think some had a fuse under small cover but I think it was for 12v plug anything 120v into the exact outlet fridge is plugged in.
